To (ZZZ whom it may concern:

Be it known that I, FRANZ A. FULLER, .a citizen of the United States,residing in Newark, county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Bag Fasteners, of whichthe following is a specification.

This invention has as its object to provide cheap, strong and effectivebag clasp, made from a single ,"iece of sheet metal blanking and 'forinig operations.

llnother purposeis to produce a clasp adapted to be hi'ngedly securedupon one of a pair of bag frame elements and so. 511-- ranged as toautomatically raise and receive the mating frame element, upon theirbeing pressed together, and prevent their separation until manuallyoperated.

A further aim is in the provision of a neat appearing clasp having noobjectionable projections and which is not readily liable to get out oforder or fail in its pur os'e.

hese objects are attained by the novel de- Sign, construction andarrangement of parts hereafter described and shown in the annexeddrawings constituting an essential part of this disclosiire, and inwhich:

Figure 1 is a plan view of a blankfrom which the preferred embodiment ofthe illvention is formed.

Figure 2 is a perspective view of the clasp as made from the blank shownin Figure 1.

Figure 3 is an interior view of a fragment of bag frame illustrating theapplication of the invention.

Figure 4 is a perspective view similar to Figure 2 but showing amodification in construction.

F ignre 5 is a similar View showing a further modification of clasp.

Figure 6 is a transverse sectional view taken on line 66 of Figure 3.

The blank, as shown in detail, comprises a plate 15, bounded bylongitudinal bending lines 16 and 17 and transverse bending lines 18 onwhich the ends 19 are turned at right angles. these ends joining thefront wall 20 of the plate adjacent the bending line 17.

Another bending line 21, parallel to line 1T. forms the inner boundaryof a lip 22 eventually curled re-entrantly over and spaced from the step20, this lip constituting the engaging portion of the clasp, ex-

tending outward over the opposed frame manner.

The line 16 bounds the base of the rear wanes (if the ens, the samebeing bent fit a right angle tot ie plate 15, foi iiiin'g in connectionwith the ends 19 and front '20. a shallow rectangular casing having anoverhanging lip 22. j The rear wall 23, near one end, has at tachedtending line 24 a narrow element 25 offset inwardly of the casing, adistance at least equal to the thickness of the niateral and then benton line 26 outwardly, parallel with the rear wall, into a detent 2Thavextending prong 28 separated from watt "235 a space 29, as well asbeing offset \vi'th' relation to it.

At equivalent distance from the opposite end of the wall 23 is a strip30 bent outward on line 31, in ah'n'eihent with the de tent 27 'ahd thencurved to present a loop 32, having a straight opening of flattenedcross section, the continuation 34 of the strip Having a peace lateralprojections 35, their Bottom resting on thei'nner surface of the plateAs the strip elements 30 and 34 are pressed tightly together, theprojections 35 are obviously brought into intimate contact with theinner face of the wall 23 ttnd are ltitt time separation by v v of thelugs 56,- format was tar sesame at at the rear wall and bent to preventany possible movement of the strip in any direction, due to theirembracing said projections, as can be clearly seen in Figure 2.

In operation, the detent 2728 is passed loosely through a slot formed inone of the frame members 10 and then moved lengthwise until the space 29is seated on the frame, at which time the loop 32 can be passed throughan appropriate opening in the frame.

A spring Wire 40, having a flattened end 41, is passed through andtightly engaged in the loop 32, its opposite end being bent outwardly,as at 42, and flattened to press against the side of the channel in theframe. adjacent its front overhanging portion 12, that portion of thewire adjacent the head 42 making contact with the inner face of thedetent 27, acting in the manner of a torsion spring to hold the clasppressed downwardly in an engaging position, but; obviously permitting itto rise upon presges and end of the strip at sure being applied to lip22, as in opening or closing the frame members, (see F igure 3).

In the modification shown in Figure 4, two loops 32 are formed in themanner described, each having projecting ears at the ends of theirinturned elements, and lugs 36'37' are provided to hold them firmly inplace, a single lug being used to engage the ends of the adjacent,central projections.

In Figure 5, there is illustrated a decided modification of loopconstruction, which will now be described. The end element 19, remotefrom detent 272S, is formed with an extending strip 50 bent to spacedlyoverlie the casing, and having, near its end, a lateral projection 51disposed parallel with the rear wall, the same being formed into a loop52 having an opening 53 and then continued, as at 54, closely againstthe element 51, projection 55 extending later ally from its end.

Like the foregoing, the end of the strip and corresponding edge of theprojection make contact with the inner surfaces of the plate 15 and arefirmly held against it and also against rear wall 23, by bent lugs36-37, as described, one or two of the lugs being used as preferred.

While the foregoing disclosure applies to preferred embodiments of theinvention, it will be understood that variations may be made in form,proportion, and detail, and it will be obvious that the structure setforth is applicable to a wider range of purposes than those indicated.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:-

1. A frame clasp comprising a plate having rear and end walls, are-entrantly turned lip extending from the front of said plate, a loopformed with said rear wall, means integral with said plate for clampingthe inner element of said loop against said rear wall, said loop beingadapted to extend through a slot in the frame, and a torsion springengaging in said loop and in contact with said frame. 2. A frame claspcomprising a plate havmg integral rear and end walls, a hooked catchformed with the rear wall, a loop, means for confining said loop to saidrear wall, said catch and loop engaging loosely in slots in the frame,and a torsion element engaging in said loop and with said catch at theinner side of said frame.

3. A device of the class described comprising a plate having anangularly disa loop and then closed tightly, the longi tudinal edge ofthe bar portion of said element being in contact with said plate, andlugs formed with one of said walls adapted to confine the bar portion ofsaid element within its assembled position.

This specification signed and witnessed this 23rd day of February, 1922.
